Yurei

A Yurei will drain a player’s sanity faster passively. For all other ghost types when your in the darkness and out of the set up time. Your sanity will drain double the amount if your dealing with a Yurei. It is also recommended to keep lights on to slow down the sanity drain, or drink sanity drinks. It has no strengths nor weaknesses.

Evidence: ghost writing, freezing temperatures, and ghost orbs.
